6 FAQs about [Energy storage can provide inertia]

Which energy storage technology provides inertia for power systems?

With a weighted score of 4.3, flywheels (with lithium–ion batteries a close second) appear as the most suitable energy storage technology to provide inertia for power systems.

Should energy storage be a virtual inertial course?

Incorporating energy storage as a virtual inertial course would require fundamental changes in grid operations and market design. Because grid rotational inertia is considered an inherent property of power generation, there is no market mechanism to include inertia generation as an ancillary service.

Are energy storage technologies a viable alternative to inertia?

Energy storage technologies have emerged as a viable alternative to providing inertia through virtual inertia, i.e. inertia generated or simulated with power electronics and controls (Zhao and Ding, 2018, Zhang et al., 2019, Fang et al., 2017a).

What is inertia in power systems?

Inertia is an intrinsic property of power systems that stabilizes the grid frequency and introduces a relationship between frequency and the balance of power supply and demand. Previously, synchronous generators and induction motors were directly connected to the power grid and were the main source of inertia (Shi et al., 2019, Lin et al., 2022).

Is system inertia necessary in the modern grid?

Findings of this study reveal that adequate system inertia in the modern grid is essential to mitigate frequency instability, thus, considering the inertia requirement of the grid in operational and expansion planning model will be key in ensuring the grid’s stability.

Is inertia important in power system optimization models?

Findings of this study reveal the following: (1) adequate system inertia in the grid is important to mitigate frequency instability in the modern grid. (2) Disregarding inertia in power system operational and expansion planning optimization models could lead to sub-optimal optimization model.
